Wood is a living material that contracts and expands with the seasons and temperature changes, which contributes to its unique and warm charm.

However, these movements can create gaps where dirt and dust can accumulate. We recommend cleaning wooden windows at least once a year with lukewarm water, a mild detergent and a cloth, without trying to strip the wood. This operation is all the more important if your region is windy or subject to strong climatic restrictions, as it will help protect and prolong the life of your wooden windows.

During this annual cleaning, it is recommended to check:

The general condition of your windows,
Condition of frames,
Condition of seals,
Condition of profiled chambers.

To protect wooden windows from the elements, it is recommended to protect them every two to three years. Whether varnish, stain, oil or paint, these products effectively protect the wood from moisture and bad weather. As well as restoring the shine to your windows, they can also give them a new look. However, it is important to use quality products and strictly follow the manufacturer's instructions to avoid damaging your wooden windows. Regardless of the type of wood or stain, regular maintenance is necessary. You can also take the opportunity to apply insect and mould repellent to the openings to make them more resistant.

Here are the steps to properly protect wooden openings:

Rub the doorframe with 10%- ammonia solution and allow to dry.
Remove partially damaged paint or varnish with a blade.
Protect your windows with adhesive tape and your floor with a tarpaulin. Also protect yourself if you use a stripper (mask, goggles, gloves and protective apron).
Sand in line with the direction of the wood grain with dry sandpaper (for new wood, use a P80 to P120 gradation) to achieve a smooth, clean surface that will be better prepared to accept any paint, varnish or oil of your choice. If your holes are very damaged, you can use a small sander, a tanner or a chemical stripper.
If you notice any major holes or cracks, fill them with sealant or acrylic rubber filler and sand them again once they have dried.
Make sure there is no dust and apply the protective layer of your choice.

If you plan to oil your wooden sashes, you can apply one or two coats with a roller or brush, making sure that the oil penetrates well into the wood.
Allow the first coat to dry before applying the next coat and carefully follow the manufacturer's instructions for optimum protection.

To clean the wood after the oil has been applied, lukewarm water with a little liquid soap can be used.

If you prefer to use varnish, it is generally recommended to apply two or three coats with a soft brush following the direction of the wood grain.

If you want to refresh the varnish on your wooden windows or change their colour, no problem. However, you will first need to prepare the surface by sanding the woodwork. Then you can move on to painting. It is best to start early in the day to allow it to dry completely before nightfall. Use flat or round brushes and a microporous acrylic paint that will allow the wood to breathe. Remember to secure the seams and glass with tape. Apply at least two coats of paint and remember to paint the hidden parts.


It is recommended not to wait until the condition of the wooden frames has deteriorated too much before carrying out maintenance. Indeed, by carrying out regular maintenance, you will avoid working harder and longer. It is best to carry out this maintenance when the weather is dry and the temperature is between 10 and 20 degrees, which will allow the paint to dry properly. It is also important to check the condition of the seals and fittings. If the seals are damaged, they should be replaced and the fittings oiled once a year.
